I solder a powerpole connector with a short bit of wire to each of the legs. Turns out the Anderson housing fits perfectly up against the gel coating. One of those and a plastic drinking cup makes a nice diffused light for living space.
If by nice you mean, only bright enough to not stub your toe while going to the bathroom in the middle of the night, sure, otherwise an utter waste of time for usable lighting in living areas unless you use quite a few of them. They're good for maybe 200lm without any diffuser over them, so a single regular light bulb is 4X as bright while most will prefer multiple times that much light in a single room.
Two issues with those are that they are highly sensitive to input voltage, so much above or below 12.0V can substantially change the output, though the human eye may not really notice it much if close "enough", and the other being that putting the diodes in so you don't have to worry about polarity, for that single moment of not having to bother with that, you forever lose 10% efficiency right off the top due to the forward drop through two diodes. The probably do it so they (at least some sellers, this jellybean design is sold under many faux brands) can market them as capable of AC as well as DC, but not so good at AC without a significant value capacitor to smooth the ripple.

Can it be battery powered?
yes
First! :)
